A green and cost-effective approach for the production of gold nanoparticles using corn silk extract: A recoverable catalyst for Suzuki–Miyaura reaction and adsorbent for removing of dye pollutants

Probing catalytic reduction on the surface of Au nanoparticles by second-harmonic generation and two-photon luminescence

“…28 Shiraishi et al studied the oxidation of ethylene catalyzed by AgNPs with gas chromatography. 29 It has also been reported that AuNPs and AgNPs can catalyze the degradation of organic dyes with the degradation process detected by UV-vis spectroscopy 30–32 and SERS. 33…”

“…28 Shiraishi et al studied the oxidation of ethylene catalyzed by AgNPs with gas chromatography. 29 It has also been reported that AuNPs and AgNPs can catalyze the degradation of organic dyes with the degradation process detected by UV-vis spectroscopy [30][31][32] and SERS. 33 In this work, we employed second-harmonic generation (SHG) and two-photon luminescence (TPL) scattered from AuNPs to investigate the catalytic reduction of aromatic nitro compounds by AuNPs in the presence of NaBH 4 with the aid of UV-vis extinction spectroscopy.…”

A review on the versatility of Carica papaya seed: an agrogenic waste for the removal of organic, inorganic and microbial contaminants in water

“…The process of adsorption is capable of eliminating both insoluble and soluble organic pollutants. [47][48][49] Biogenic adsorbents have been synthesized from biodegradable agricultural waste such as Carica papaya seed (CPS), 48,50,51 plantain peel, 52,53 orange peel, [54][55][56] carrot powder, 57 coconut shell powder, 58,59 rice husk, 60,61 sugar cane bagasse, 62,63 corn silk 64,65 and inorganic materials like clay minerals to improve efficiency or adsorption capacity. These materials act as a support in adsorption and, most significantly, in synthesizing photocatalysts to offer a higher specific surface area and strong adsorption affinity towards the pollutants.…”

Ag nanoparticles stabilized on basalt fibers as a novel, stable, and reusable catalyst for Suzuki–Miyaura coupling reactions

“…[23] Fe 3 O 4 -Au@SF-SBA-15 as another magnetic catalyst was studied in Suzuki-Miyaura reaction. [24] Also, there are some reports that bimetallic NPs are successfully used for this coupling reaction as a catalyst. Bimetallic Pd-Ni core-shell NPs were reported as effective catalysts for the Suzuki reaction.…”
